Description

Enjoy large images in small rooms with the ViewSonic LS831WU 4500-Lumen WUXGA Ultra-Short Throw Laser DLP Projector. Its 4500 lumens of brightness can overcome ambient light in many situations, and its ultra-short 0.252:1 throw ratio make it a suitable option for small, well-lit small presentation areas. The WUXGA 1920 x 1200 native resolution is suitable for displaying many file and document types. The LS831WU has two HDMI inputs for connecting digital high-definition sources such as Blu-ray players and HD cable/satellite boxes. The projector also has a VGA input for analog sources, plus an RCA composite video and S-Video input. Its HDMI inputs are 3D-capable for viewing 3D Blu-ray discs with other compatible equipment, which is available separately. An HDBaseT port lets you run a single RJ45 cable to provide uncompressed audio and HD video over long distances. A VGA output allows daisy-chaining of multiple projectors or displays. The LS831WU includes a VGA cable and an IR remote control as an added convenience.
